LOCK FO R RAILROAD SWITCH-STANDS.

SPECIFICATION forming part of Letters Patent No. 316,545, dated April28, 1885.

Application filed October 6, 1884.

- drawings.

Figure 1 is a top view showing the operating-lever in a horizontalposition. Fig. 2 is a side view showing the operatinglever in bothhorizontal and vertical positions, the latter being in the position ithas when locked, and is indicated by dotted lines. Fig. 3 is a sectionaldetail taken through the lock transverse the operating-lever, showingthe lock closed.

This invention relates to a locking mechanism to be used with railwayswitchstands; and it consists in the construction hereinafter set forth.7

In the annexed drawings,the letter A indieates the switch-stand, onlythe horizontal top being shown, that being sufficient to show theconnections. Through this passes the usual switch-rod, 13, having thearm 0 at the bot tom for connection with the switch. This top A is madewith several vertical notches, a a a &c., at its edge, there being anumber corresponding to the number of positions the switch is to have.

Secured to the rod B, just above the top A, is the operating-lever D,extending horizontally from the rod B and just over the top A. Thislever D consists of a main portion, d, which is rigidly held to the rodB, and a handle, d, which is hinged to the main portion 01, so that suchhandle can be turned down; but when lifted up the handle can only beraised far enough to align itself with the portion (1, and thus be in ahorizontal position. At its junction with portion d the handle d is recessed, as at g, in which recess is placed a lock, such recess 9 beingbeyond the end of the portion d. This lock consists of a bolt, 6, havingthe springs c and d, for holding it, as indicated. This bolt also has anotch, b, for engagement with the rib f when the device is locked.

In the top A, at the side of each notch a a a, &c., is made a recess,for catching the bolt b.

(No model.)

it is a key adapted to the look.

In use the handle d is held horizontally until the rod B is turned theproper distance and the switch is at the proper position. The handle atis then turned down into the notch at that point, and the spring 0shooting the bolt 12 into recess 9, and the spring (1 pressing the saidbolt 1) so that the rib fcatches in the notch 12, the handle is lockedagainst accidental or intentional displacement until the key isused toretract the bolt. Thus the two springs act upon the bolt 0, to throw itinto the recess g, and d, to hold it on the rib f. The lever is unlockedby retracting the bolt I) with the key h. This device thus secures theswitch at its proper point, and the switch cannot be moved until theloci; is released. The locking is done automatically. As soon as thehandle is turned down into the notch the bolt shoots, and there is nodelay in turning bolts or slipping pins. Besides,only the proper personwith the key can loosen the lever. The lock, being in the lever, isprotected from weather, and also from being tampered with.

Having described my invention, what I claim is 1. The switch-stand A,having in its top the vertical notches a a a and recesses g at suchnotches, and the switch-rod B, passing through such top, in combinationwith the lever D, secured to the rod B, and consisting of the twoportions d d, hinged together, and a bolt, 1), located in the handleportion d at the top of the stand, as set forth.

2. The switch-stand A, having in its top the vertical notches a a a andrecesses g at such notches, and'the switch-rod B, passing through suchtop, in combination with the le' ver D, secured to the rod B, andconsisting of the two portions d d, hinged tog-ether,the handle portiond having the recess 9 and the rib f in such recess, and the bolt bhaving the notch b and the springs c and d located in said recess 9, allconstructed, combined, and arranged as and for the purpose set forth.

In testimony whereof I aliix my signature in presence of two witnesses.

EDWARD HILLERY.
